In real life, especially sports, movements do not occur along a single joint or
a single plane of motion.
If you constantly perform exercises with a short range of motion in
a single plane of motion, your muscles will be shortened, your joints will be less than optimally mobile and functional, and eventually your performance will suffer.

Hang a weight on the end
of an 18 - inch string and set it in
motion like a pendulum, moving back and forth horizontally in a
single plane (its speed gradually accelerates as it approaches the center and decelerates again as it reaches the top at the other end).
The bag allows you to move in all three
planes of motion during a
single exercise.
Traditional PNF techniques involve doing the stretches in diagonal or spiral
motions to promote movement through various
planes of motion, while contract - relax movement patterns tend to involve
single - joint
motion through one
plane (see the sidebar «Proposed Mechanisms
of PNF Stretching: The Controversy»).
